Anxiety about boyfriend leaving

What are ways to cope with this besides seeing a psychiatrist? Does this mean something is wrong with me? Every time my boyfriend goes to work I constantly worry about him and fear something will happen. It also makes it so much worst that our phones are off at the moment so I have no idea if he made it okay each day and is fine for almost 12 hours a day for work. I constantly think, worry, and miss him. Also I can't stand sleeping without him I feel at ease every night in his arms or beside him. Could it be the pregnancy hormones or something else?
